Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a safety belt attachment for attaching a safety belt to an existing pipe installed to prevent a fall accident when working on the upper part of a vehicle such as a tank truck.

When working on top of vehicles such as tank trucks or in high places with scaffolding for construction work, etc., workers should wear safety belts and hang from the top to prevent accidents such as falling of workers. The work is performed in a state where the hook of the safety belt is attached to the equipment such as the existing pipe that has been installed (see Patent Document 1). In this way, field workers are protected by safety belts so as not to fall from vehicles or scaffolds, enabling safe work.

Various types of existing pipes are installed at work sites. For example, there is an existing pipe in which pillars suspended from above are connected to the pipe at predetermined intervals, as described above. In the case of such an existing pipe, when a worker attaches a safety belt hook and performs work that involves movement, he/she moves along the existing pipe with the safety belt hook attached in places where the support is not connected. Although it is possible, it is necessary to once remove the safety belt hook from the existing pipe at the point where the strut is connected, reattach it to a position beyond the connection point of the strut, and move it.

In this way, when working with a safety belt hook attached to an existing pipe that is suspended from above via a support, not only does smooth movement become impossible, but the safety belt hook needs to be removed once. It also compromises safety.

Specific embodiments of the present invention (hereinafter also referred to as "present embodiments") will be described in detail below. In addition, the present invention is not limited to the following embodiments, and various modifications are possible without changing the gist of the present invention.

≪1. Safety belt mounting attachment≫
The safety belt attachment according to the present embodiment is an attachment for attaching a safety belt to an existing pipe to which struts suspended from above are connected at predetermined intervals.

An existing pipe is an existing pipe installed to prevent a fall accident when working on top of a vehicle such as a tank truck or in a high place with scaffolding. Work after installing. In particular, the existing pipe is one in which struts suspended from above are connected at predetermined intervals. In addition, although the size such as the diameter of the existing pipe is not particularly limited, a pipe of a general size can be used.

Conventionally, when working at a high place as described above, hooks provided on a safety belt (safety belt hooks) are directly engaged with existing pipes. However, the existing pipe is connected to a post suspended from above at a predetermined interval, and when the existing pipe is moved with the safety belt hook locked, the safety belt hook will be broken at the position of the post each time. Therefore, it is necessary to remove it and attach it by newly locking it at a place beyond the support.

The safety belt mounting attachment according to the present embodiment is intended to eliminate such inconveniences of the conventional work. It eliminates the need to remove it each time, and makes it possible to work at heights safely and efficiently.

1 to 3 are diagrams showing an example of the configuration of a safety belt attachment according to this embodiment. 1 is a perspective view, FIG. 2 is a front view, and FIG. 3 is a plan view.

Specifically, the safety belt attachment attachment 1 includes a rod-shaped body 11, a plurality of ring-shaped clips 12 arranged on the rod-shaped body 11 at substantially equal intervals, and a safety belt locking clip for locking the safety belt. a part 13; The safety belt attaching attachment 1 is used by passing the existing pipe 2 through the ring holes 12H of all the ring-shaped clips 12 and locking the hook S of the safety belt to the safety belt locking portion 13 .

In addition, although the details will be described later, by using the safety belt mounting attachment 1, when the worker moves, the ring-shaped clip 12 is slid while the existing pipe 2 is being passed through, and the existing pipe 2 is connected. At the position of the post 21, the clip portion 12C of the ring-shaped clip 12 can be passed while being pressed against the post 21. As shown in FIG. As a result, there is no need to remove the safety belt each time the post 21 of the existing pipe 2 is connected, and efficient work becomes possible.

[Rod-shaped body]
The rod-shaped body 11 is made of, for example, a steel pipe, and is joined with a ring-shaped clip 12, which will be described later. A safety belt engaging portion 13, which will also be described later, is connected to the rod-shaped body 11. As shown in FIG.

The rod-shaped body 11 is not particularly limited, but may be, for example, a cylindrical body having an outer diameter of about 30 mm to 50 mm. Also, the length is not particularly limited, and can be, for example, about 200 mm to 400 mm.

It is preferable that the safety belt mounting attachment 1 can be easily carried by the operator and can be easily attached when working at a high place. When each member constituting the safety belt mounting attachment 1 is large and heavy, it imposes a heavy burden on the worker, which may cause a loss of safety. Therefore, it is preferable to set the size, material, etc. of each member constituting the safety belt attachment attachment 1 in consideration of these points.

[Ring clip]
The ring-shaped clip 12 is a clip having a ring shape and having a ring hole 12H and a clip portion 12C. The ring hole 12H is a substantially circular hole, and preferably its hole diameter (ring diameter) is larger than the cross-sectional diameter of the rod-shaped body 11 described above.

Here, when using the safety belt attachment 1, the existing pipe 2 is passed through the ring hole 12H of the ring-shaped clip 12 (see also FIG. 4). Therefore, the diameter (hole diameter) of the ring hole 12H needs to be larger than the outer diameter of the existing pipe 2 . Specifically, the diameter of the ring hole 12H of the ring-shaped clip 12 is not particularly limited as long as it is larger than the outer diameter of the existing pipe 2, but is preferably about 70 mm to 100 mm, for example.

As shown in FIGS. 1 to 3, a plurality of ring-shaped clips 12 are arranged on the rod-shaped body 11 at substantially equal intervals. 1 to 3 show an example in which four ring-shaped clips 12 are provided, but the present invention is not limited to this as long as the number is plural. Among them, an even number such as 2, 4 or 6 is preferable, and 4 as shown in the figure is particularly preferable. By providing an even number of ring-shaped clips 12 on the rod-shaped body 11 in this manner, the safety belt engaging portion 13, which will be described later, can be positioned near the central portion of the rod-shaped body 11, and the existing pipe 2 can be secured. Improves stability when attached. In particular, by setting the number of ring-shaped clips 12 to four, it is possible to further improve the efficiency of carrying and working in high places without increasing the weight of the safety belt mounting attachment 1 .

1 to 3, the ring-shaped clip 12 is joined onto the rod-shaped body 11 with the clip portion 12C facing upward. That is, the clip portion 12C is joined onto the rod-like body 11 so that the clip portion 12C is positioned symmetrically with respect to the joining portion with the rod-like body 11. As shown in FIG. Although details will be described later, when the safety belt mounting attachment 1 is attached to the existing pipe 2 to which the struts 21 are connected at a predetermined interval, the clip portion of the ring-shaped clip 12 is moved along the existing pipe 2. By pressing 12C against the strut 21, it can pass through the part where the strut 21 is connected. On the other hand, for example, if the ring-shaped clip is joined to the rod-shaped body with the clip facing sideways or downward, the clip will not come into contact with the strut 21 when moving along the existing pipe 2, and the strut 21 will physically move. It becomes an obstacle and it becomes impossible to pass through the part of the support 21, and it is necessary to remove it each time as in the conventional case.

Note that the ring-shaped clip 12 can be joined to the rod-shaped body 11 by welding or the like.

[Safety belt locking part]
The safety belt locking portion 13 is a member for locking the safety belt, more specifically, for locking a hook (safety belt hook) S provided on the safety belt (see also FIG. 4). reference). Thus, in the safety belt attachment attachment 1, the safety belt (a part of the safety belt) is attached to the safety belt locking portion 13. As shown in FIG.

As shown in FIGS. 1 to 3, the safety belt engaging portion 13 is composed of, for example, a ring-shaped wire, shackle, or the like, and is constructed by passing the rod-shaped body 11 through the hole of the ring. The safety belt engaging portion 13 is positioned between a plurality of ring-shaped clips 12 arranged on the rod-shaped body 11 . For example, in the example shown in FIGS. 1 to 3, four ring-shaped clips 12 are joined to the rod-shaped body 11, the second ring-shaped clip 12 and the third ring-shaped clip counting from one end of the rod-shaped body 11. 12, a safety belt engaging portion 13 is positioned and configured.

As described above, the safety belt engaging portion 13 is a member to which the safety belt hook S is engaged. The two ring-shaped clips 12 (in the example shown in the figure, the second and third ring-shaped clips 12 counting from one end) act as stoppers to prevent the safety belt locking portion 13 from falling off the rod-shaped body 11. be able to. Thereby, worker safety can be improved. Also, as described above, by joining an even number of ring-shaped clips 12, the safety belt engaging portion 13 can be positioned near the center of the rod-shaped body 11 as in the examples shown in FIGS. can be balanced, and can be attached to the existing pipe 2 more stably.

In addition, the safety belt engaging portion 13 may or may not be joined to the rod-shaped body 11 . In a mode in which the safety belt engaging portion 13 is not joined to the rod-shaped body 11, as in the example shown in FIGS. The safety belt engaging portion 13 can be moved at a distance from the clip 12 . As a result, when moving along the existing pipe 2, the movement can be facilitated by pressing the safety belt engaging portion 13 against the ring-shaped clip 12. As shown in FIG.

≪2. Using the safety belt attachment≫
As described above, the safety belt attachment attachment 1 includes a rod-shaped body 11, a plurality of ring-shaped clips 12 joined to the rod-shaped body 11 with the clip portion 12C facing upward, and a safety belt for locking the safety belt. A locking portion 13 is provided.

As shown in FIG. 4, the safety belt mounting attachment 1 is used by passing the existing pipe 2 through the ring holes 12H of all the ring-shaped clips 12 and locking the safety belt hook S to the safety belt locking portion 13. As shown in FIG. In addition, since the ring-shaped clip 12 is joined to the rod-shaped body 11 with the clip portion 12C facing upward, the clip portion of the ring-shaped clip 12 can be positioned on the axis of the existing pipe 2 to which the strut 21 is connected. 12C is applied.

Here, for example, when working in the upper part of a vehicle such as a tank truck or in a high place where scaffolding is assembled, the worker moves and works along the existing pipe 2 that is continuously provided. Become. Therefore, the operator maintains the state shown in FIG. 4 and moves the safety belt attachment 1 while sliding it along the existing pipe 2 .

In the existing pipe 2, where the strut 21 is not provided, it becomes possible to move easily by simply sliding the safety belt mounting attachment 1. - 特許庁However, when reaching the location where the support 21 is provided (the location indicated by "X" in FIG. 4), the support 21 becomes a physical obstacle.

At this time, the safety belt mounting attachment 1 according to the present embodiment is provided with a ring-shaped clip 12, which is used by passing it through the ring hole 12H of the existing pipe 2, and the clip portion 12C is attached to the post 21 of the existing pipe 2. It is provided so as to be in a contact position. Therefore, when moving, by pressing the clip portion 12C of the ring-shaped clip 12 against the support 21 of the existing pipe 2, it is possible to easily pass through the place where the support 21 is connected.

FIG. 5 is a diagram for explaining how the clip portion 12C of the ring-shaped clip 12 passes through the support 21. As shown in FIG. As shown in FIG. 5, the safety belt mounting attachment 1 is slid along the existing pipe 2 in the direction of the arrow in the drawing, and the clip portion 12C of the ring-shaped clip 12 is pressed against the support 21, whereby the ring-shaped clip 12 is , the clip portion 12C is bent to partially open the ring (state indicated by "Z" in FIG. 5). Similarly, in the other ring-shaped clips 12 that are joined in plurality, the rings are similarly opened through the clip portions 12C, so that the safety belt attachment attachment 1 can pass through the positions of the posts 21 sequentially. .

Thus, since the safety belt attachment 1 is provided with the ring-shaped clip 12, it is possible to pass through the support 21 of the existing pipe 2, which is a physical obstacle, through the clip portion 12C. Thus, it is not necessary to remove the safety belt each time it passes through the post 21, and it is possible to move at a high place extremely efficiently. In addition, since there is no need to remove the safety belt, the safety of working at heights can be further enhanced, and work efficiency can be improved.
